the virtual volume has been create,,now the problem i am still error meshing virtual volume.
On the transcript list : error meshing volume v-volume 1 aborted due to poor mesh quality. The user may proceed by first remeshing the faces with the poor mesh quality.
volume v-volume 1 could not be meshed without face(s) successfully meshed.
What should i do??

You need to do what gambit says: fixing the poor surface mesh.
you certainly have other warnings regarding surfaces which cannot be meshed successfully. Sometimes Gambit gives the surface ID, where meshing has failed.
So just see how looks the given surface(s)
And fix the problem

try to find why.
Check where are those negative volumes (examine mesh, choose volume in the quality panel)

once volume mesh failed, go to examine mesh, select 2d, and enable worst elements.
Gambit will display the worst 2d-element which should be source of your error message
